Mission Frame and Fork

Build your own bicycle

Our frames are hand welded of double butted 4130 Chromoly steel. They're light but extremely durable and guaranteed for 50 years.

Valencia: Our single speed frameset for freewheel and fixed gear riders.

Sutro: Our internally geared frameset. We've opened the rear dropouts wide for internal hubs and routed both the rear brake and shift cables through the frame internally.
